Treatment Planning Completes Flashcards
When is bone resorption most rapid?
In the first 6 months following xla
None resorption in anterior mandible is four times fresher than maxilla
Where should the post dam be placed?
Soft tissue At or along the junction of the hard and soft plate where pressure within physiological limits can be applied to aid denture retention
Needs to be anterior to palatine fovea which area collection of minor salivary glands just anterior to vibratory line
What factors will include mandibular bone loss?
Functional force Bone type Blood supply; Age Diet and deficiency
What are the forces acting to keep the denture in situ?
Physical
Mechanical
What are the physical forces keeping the denture in?
Adhesion cohesion Gravity Base adaptation Viscosity Surface tension: negative surface of denture becomes wet by saliva and along periphery there is a negative pressure which prevents due true being drawn away
What are the mechanical forces keeping the denture in?
Undercuts
Muscular
What is adhesion and cohesion optimised by?
Accurate fit
Optimum surface area
Peripheral seal: needs to fill functional sulcus
What is the Hamilcar notch?
Overlies gap between pterygoid hamulis and maxillary tuberosity
This is the most posterior extension
How far up the RM pad should the teeth be placed?
2/3
Thine anterior part is firm and fibrous
The posterior part is mobile
Whag is th significance of the mylohoyoid ridge?
With age this becomes more prominent and then can lead to mucosa soreness
What are the options for a patient with denture dissatisfaction?
Reline/repair
Fixed implant retained
New denture: conventional or special techniques
What are the special techniques that can be used in completes?
Copy Impression technqiue Occlusal techqniue Nutrual zone Soft linings Denture base matal Implant retained
What are the impression techniques available?
Standards
Border moulding
Mucodisplasive
Flabby ridge
Border moulding includes what?
Shaping of the impression material by manipulation of the soft tissues
What is the neutral zone techqniue?
This is an impression techqniue to record the neutral zone and this where the polished surfaces should be placed to increase stability
